Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532554, here are decompositions:

3 + 31532551 = 31532554
47 + 31532507 = 31532554
293 + 31532261 = 31532554
491 + 31532063 = 31532554
587 + 31531967 = 31532554
827 + 31531727 = 31532554
887 + 31531667 = 31532554
1031 + 31531523 = 31532554

Showing the first eight; more decompositions exist.
